When creating a cross-section, all properties are defined which are necessary for a structural analysis (surface, moment of intertia, section modulus). A distinction is made between various cross‑section types, such as rectangular or composite cross-section.
One cross-section has to be assigned to each member in RFEM and RSTAB. Many cross-sections are already stored in the library and can be selected there.
